T0 (ZZZ 1071,0771. it may concern:

Be it known that I, Josnrrr Dr DARIO, a citizen of the United States, residing at Attleboro, in the county of Bristol and State of Massachusetts, have invented certain new and useful Improvements in Heaters for Rotary Burnishing Irons; and I do declare the following to be a full, clear, and exact description of the inventiomsuch as will enable others skilled in the art to which it appertains to mali e and use the-same.

My invention has for its object to provide an extremely simple and inexpensive, yet an efficient and desirable heating attachment for shoe repairing andsole-burnishing mahine h ving a rot y bu n ng iron, f tion alone being relied upon to heat the iron, whereby the eXpen-se and inconvenience of gas h aters is o iated- Tn & he Qu the a ove and a p vot d arm is povided for contact with the burshi g i on and furthe obje of th invention is to provide a latch which is actuated by a spring to normally hold the arm in contact with the burnishing iron, said latch however being also operable to retain the arm in an inoperative position, when it is moved by hand tosnch a position.

The pivoted arm is provided with a friction shoe for contact with the burnishing iron, in the preferred form of construction, and a further aim of the invention is to provide. novel means whereby this shoe may be dctachably secured to the arm, so that it. may be renewed whenever desired.

lVith the foregoing in view, the invention, resides in the novel subject matter hereinafter described and claimed, the description being supplemented by the accompanying drawing.

Figure 1 is a perspective View of a portion of a sole finishing machine, showing the application of my invention for heating the edge setter, which is merely a rotary burnishing iron for shaping and burnishing the edge of the shoe sole.

Fig. 2 is a side elevation of the invention showing associated parts of the burnishing machine in section.

In the drawing above briefly described, the numeral 1 designates the arbor of a sole finishing or burnishing machine, this arbor being rotatable in bearings at the upper ends of vertical standards or frames, one of these hearings being indicated at 2, while its car rying standard or frame is designated by which, in the form of construction herein disclosed. is provided with a laterally exs tending foot 7 having a transverse, groove 8 to receive the upper portion of the rod 4. A clamping member 9 is provided at the lower side of the foot 7 and is formed with a groove 10 t0 receive the lower portionof the rod 4, clamping bolts 11 being passed through the foot 7 nd the member9 for clamping them tightly around the rod 4, to.

holdthe post 6 in uprightposition. Pivoted between its ends to the upper end of the post 6 as indicated at 12, is a horizontal' vertically swinging arm 13, the upper end .Of saidpost being preferably bifurcated as indicated at 14 for the reception of said arm. In the form of construction herein disclosed, the front end of the arm13 is provided with a friction shoe 15 formed of rubber orany other suitable material and adapted to contact with the rotary burnishing iron 5. 1V hil'e any suitable means may be employed for detachably securing the shoe 15 upon the arm 13, I prefer to provide a pair of clamping plates 16 secured against opposite sides of the arm by screws or the like 17, said plates extending below said arm to clamp against opposite sides of a rib 18 with which the shoe 15 may be provided. If desired, the rib and the coacting portions of the plates 16 may b of dove-tail formation as shown in Fig. 1.

I have shown. a coil spring 19 connecting the front end portion of the arm 13 with the post 6 and exerting a downward pull on said arm to assist in properly holding the shoe 15 in contact with the burnishing iron '5. A spring operated latch 20 also asists in this operation, and will be fully described below.

The latch 20 is in the form of a substantially straight arm having its lower end pivot-ed at 21 to the post 6 at a pointspaced below the arm 13, said latch converging rearwardly with the rear end of said. arm 13 and being held in contact with the beveled rear extremity of this arm, by a coiled spring 2-2. By pivoting the latch 20 in the manner set forth, spring 22 pulls it upwardly against the rear end of the arm 13, thereby tending to swing the front end of this arm downwardly vand increasing the friction existing between the shoe 15 and the burnishing iron 5. It will be obvious that it the spring 22 is of suiiicient strength, the

- heater is provided which is of simple and inexpensive construct-ion, yet it will be highly efiicient and inf every way desirable. Whenever the use of the device is not necessary, it may be held in an inoperative posi- 'tion by the latch 20 and it will be obvious that the shoe 15 may be renewed whenever desired.

As excellent results may be obtained from the details disclosed, they are preferably followed, butwithin the scope of the invention as claimed, numerous minor changes may be made.

I claim 1. A heater for a rotary S0le-burnisher comprising a post, means for securing it to a frame of a sole-burnishing machine, a vertically swinging arm pivoted to said post and adapted to contact with the burnishing iron, a spring acting on said arm for holding the same in tight contact with the iron, and a latch associated with said arm and post for holding the arm in inoperative position when desired.

2. A. heater for a rotary sole-burnishing iron comprising a pivoted arm and means for mounting it on the frame of a. soleburnishing machine, and a spring-actuated latch normally bearing against said arm to force it against the burnishing ironfsaid latch being operable to hold the arm in an inoperative position when moved to such a position.

3. A heater for a rotary sole-burnishing iron comprising a support and means for mounting it on the frame of a sole burnishing machine, an arm pivoted between. its ends to said support and having one end adapted to contact with the iron, a latch pivoted-to said support below said arm and converging with the other end of the latter, and a spring tending to move said latch constantly upward whereby to force against said arm and hold it in operative position, said latch and arm being cooperable to hold the latter in inoperative position when moved to such a position. 4. A heater for a rotary burnishing iron comprising a shoe for contact with the iron, a carrying member for said shoe, and a pair or clamping plates secured against opposite sides of said shoe and arm for holding the one on the other.

In testimony whereof I have hereunto ai fixed my signature. i
